The rod has at the forward end a piston head provided with a rearwardly extending sleeve which is placed into sealed locking engagement with the end cover after the specimen has been introduced or drawn into the vial. The combination of the cap at one end and the cover member at the other end provides a complete seal for the container. The piston rod has two portions which can be severed from each other.
